Increasingly, the answering machine is no longer a separate physical device, but it is provided as a feature by the telephone network provider. The answering machine stores messages and data on central servers, and can be enabled and configured through the local phone. Messages are listen to via the telephone. This solution offers the advantage that no separate answering machine is required at the customer's home. The function is independent of whether the actual connection is available and can, for example, record messages when there is a local fault on the telephone or line.
The modern Voice over IP telephony and cloud PBX systems mostly provide answering machine features centrally in the form of a voicemail box as standard. Thanks to the linking of computers and telephones through Internet technology these answering machines can now offer numerous additional functions.
